This is not good. This is a system that has been recently rebooted, and
come up clean. This i sthe very first LVM command I have run by hand
since the boot.
In terms of the other problems I was having, I think I _may_ have gotten
those fixed (i.e., things like `find /` killing the system) by some
friendly souls in the linux-kernel mailing list with a VM patch. There
seemed to be a bug in largemem systems that was being exercised.
Now, I just rebooted the system with that patch on a fresh kernel:
Linux Kernel 2.4.19, patched with the VM patch, LVM 1.0.5 and Broadcom
Gigabit Ethernet patches.
I left for dinner, during which time nobody did anything to the
machine. I came back and decided to try creating a snapshot volume of
/dev/vg00/tmp, and lvcreate segfaulted. lvscan also segfaults, vgscan
hangs, and vgdisplay and lvdisplay seem to still work.
trying to create a test volume after that (`lvcreate --extents 512
--name testvol vg00`) simply hangs.
So, who do I give what information to so that we can trace down the base
of this problem, and get a fix? Ask me for whatever you need from the
system, and I'll provide it if I can.
Thanks again in advance,
Gregory
